Abstract

Abstract : A multifunctional Eu-CP (1 ) as a recyclable luminescent probe for the highly sensitive detection of Fe 3+ /Fe 2+, Cr2 O7 2−, and nitroaromatic explosives. Abstract : A novel 2D lanthanide coordination polymer {Eu-CP (1 )} based on a 3-bis(3-carboxyphenyl)imidazolium (L) ligand was successfully assembled through a solvothermal method. Luminescence tests indicate that1 has excellent selectivity and sensitivity to detect Fe 3+ /Fe 2+, Cr2 O7 2−, and a series of nitroaromatic explosives. Interestingly, 1 can effectively distinguish Cr VI anions (CrO4 2− /Cr2 O7 2− ), which is difficult for most of the reported CPs. Furthermore, in the detection process, 1 can be simply and quickly regenerated and reused at least five times. As far as we know, 1 is the first multifunctional Eu-CP used as a luminescent probe to detect Fe 3+ /Fe 2+, Cr2 O7 2−, and a series of nitroaromatic explosives (NAEs) based on the imidazolium derivative.
